ARTHUR GEORGE MUMFORD, OF COLCIIESTER, ENGLAND.

FEED-WATER REGULATOR FOR BOILERS.

SPECIFICATION forming part of Letters Patent No. 607,261, dated July 12,1898.

Application filed December 28, 1897. Serial No. 664,060. (No model.)Patented in England May 2, 1897, No. 9,307.

To all whom it may concern.-

Be it known that I, ARTHUR GEORGE MUM- FORD, a subject of the Queen ofGreat Britain, residing at OOlCl16St61,ll1 the county of Essex, England,have invented a new and useful Feed-lVater Regulator for Boilers, (forwhich I have obtained a patent in Great Britain, No. 9,307, bearing dateMay 2, 1897,) of which the following is a full and completespecification.

This invention relates to an improved apparatus for automaticallycontrolling the supply of feed-water to water-tube and othersteam-generators, the object being to maintain a constant water-level inthe boiler under all working conditions.

This invention consists in the novel construction and combination of theparts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section of the device. Fig.2 is a sectional plan View.

A is a chamber containing a float B.

A is a chamber containing a valve 0 and connected to the chamber A. Apipe a connects the upper part of the chamber A with the steam-space ofa boiler, and a pipe a connects the lower part of the chamber A with thewater-space of the boiler. -The chamber A is connected with thefeed-water supplypipe of the boiler by pipes c and c.

D is a lever secured on a spindle F inside the chamber A. The lever Dprojects into the chamber A and is connected to the float B by a link E.The spindle O of the valve 0 is pivoted to the lever D bya pin f, sothat the said valve is controlled by the float.

The valve-spindle O is adjustable in length, being formed of two parts,which are screwed together. The length of the spindle is changed so asto alter the working level of .the water in the boiler by means of aspindle J, which works in a stufling-box a. The inner end of the spindleJ has a socket j, which engages with a square projection 02 onthe'valve-spindle, and the outer end of the spindle J has a hand-wheel Kfor revolving it.

L is an indicator operatively connected with the spindle J and showingthe working position of the float.

The spindle F is j ournaled in a stufling-box on the chamber A, and O isan arm or lever secured on the projecting portion of the spindle F.

N is a lever pivoted 011 a pin a, which pro jects from the chamber A.One end of the lever N is pivotally connected with the lever O by a linkP, and the other end of the lever N carries an adjustable weight M forbalancing the float.

What I claim, and desire'to secure by Letters Patent, is-

1. In a feed-water regulator, the combination, with a casing providedwith boiler c011- nections, a fioat, a valve in the feed-water pipe, alever D arranged inside the said cas= ing and operatively connected withthe said float, a valve-spindle adjustable in length and connecting thesaid valve and lever, and a pivot-spindle F secured to the said leverand projecting from the casing; of a pivoted balance-lever operativelyconnected with the projecting end portion of the said spindle F; andmeans for varying the length of the said valve-spindle, substantially asset forth.

2. In a feed-water regulator, the combination, with a casing providedwith boiler connections, a float, a valve in the feed-water pipe, alever D arranged inside the said casing and operatively connected withthe said float and valve, and a pivot-spindle F secured to the saidlever and projecting from the said casing; of a pivoted balance-lever,an arm secured on the said spindle outside said casing, and a linkpivotally connecting the said arm and balance-lever, substantially asset forth.

ARTHUR GEORGE MUMFORD.
